    Abstract: An aerodynamic hub assembly for a wind turbine is disclosed. The hub assembly may include a hub extension, a rotor blade having a blade root and a blade tip, and a hub airfoil section mounted at least partially over the hub extension. The hub airfoil section may be fixed relative to the rotor blade or may be configured to rotate about a common pitch axis with the rotor blade. The hub extension may be connected to and extend radially from a center of the hub assembly. Further, the hub assembly may include a pitch bearing having an inner race and an outer race, wherein the pitch bearing may be coupled between the hub extension and the blade root. Additionally, the hub assembly may also include an aerodynamically-shaped spinner, wherein the spinner may house at least a portion of a root structure extending radially from the center of the hub assembly.

    Abstract: The present disclosure is directed to a drivetrain assembly for a wind turbine. The drivetrain assembly includes a gearbox having a ring gear, an annular torque support, and at least one flexible component configured therebetween. More specifically, the ring gear includes opposing inner and outer circumferential surfaces separated by side circumferential edges. The side circumferential edges include a rotor-side edge and a generator-side edge. The rotor-side edge has a first set of circumferentially-spaced teeth. The torque support has a generator-side surface having a second set of circumferentially-spaced teeth. Thus, the first set of teeth of the ring gear are configured to engage the second set of teeth of the torque support so as to couple the ring gear to the torque support. In addition, the flexible component is configured between the first and second sets of teeth so as to control vibrations in the wind turbine, e.g. transmission of gearbox-generated vibrations. Thus, location of the flexible components allows for improved bedplate stiffness of the wind turbine.

    Abstract: A modular gearbox assembly for a wind turbine having improved up-tower serviceability includes a low-speed gear stage module, a separate, intermediate-speed gear stage module adjacent to the low-speed gear stage module, and a separate high-speed gear stage module adjacent to the intermediate-speed gear stage module. The gearbox assembly also includes a first flange removably connecting the intermediate and high-speed gear stage modules and a second flange removably connecting the intermediate and low-speed gear stage modules. Thus, the low-speed gear stage module converts a low-speed, high torque input from a rotor shaft of the wind turbine to a high-speed, low torque output for a generator of the wind turbine via the intermediate and high-speed gear stage modules. In addition, the first and second flanges allow for easy disassembly of the gear stage modules such that the various stages can be easily repaired, replaced, and/or inspected.
